Questions tagged [navigation]

Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. Robot navigation includes exploration, mapping, localization, path planning and path execution

i have one robot, i have to get the initial location of that robot. then when we move the robot from that location, and when we give the command like "HOME" then it should go that initial location. ...

I'm trying to understand these two classic approaches to path planning in dynamic environments/with moving obstacles.
According to some review papers, there seems to be quite a difference between them,...

Is their any method by using which I can find a space or gap in given point cloud which has size greater than given rectangle of size $l*b$ or a circle of radius $r$? This way my robot can make a path ...

I'm looking Indoor GPS system for agriculture tasks in a greenhouse.
I want to make an autonomous robot who can navigate by "GPS", I want the system to be 3D (x,y,z) and allowing the I can use robotic ...

My question concerns the proper way to implement a Kalman Filter using range only information for localization. Imagine I have a robot moving within an environment and over time he receives some range ...

I'm designing a line following robot that can navigate to different points in a map that can be represented by graph theory. I have implemented a dijkstra algorithm, which provide the correct path to ...

I need a covariance of parameter estimation for reliability estimation. According to the this post, I know the approximation of the Hessian can be calculated as
$$ \sigma^2 H^{-1} = C $$
where H is ...

I have been asking a couple of questions here and around on autonomous boats and finally I decided to post the design and gather some feedback.
The idea is to build a small vessel capable of advanced ...

I'm reading Mechanics of Robotic Manipulation by Matthew T Mason and I stumbled upon the concept of kinematic constraints. The book mentioned about two types of constraints: holonomic and nonholonomic ...

I am trying to implement FastSLAM 1.0 and I am using sensory and control data acquired from Pepper via ROS to evaluate my implementation. However I am having major issues when I try and control Pepper'...

I am trying to move a robot in a straight line from point A, to point B. The robot's primary sensor is a Hokuyo URG-04LX-UG01 LIDAR that gives me the magnitude and direction of each point it detects ...

I have a mobile robot which receives GPS position (lat/lon) and has an IMU for handling gaps in GPS service.
I want to be able to conduct short distance planning in a Cartesian plane, but the robot ...

As a part of my research work I'm supposed to build or use an existing autonomous vehicle simulator, in which I can also control the behaviour of the traffic in the system, I was searching on Google ...

The idea of using Kalman gain in EKF SLAM is to figure out how much we trust our motion model and sensor/observation model. As explained in The Extended Kalman Filter: An Interactive Tutorial for Non-...

I've been looking into path planning for a non-holonomic robot with 3 DOF in a 2D plane and recently learned about Voronoi diagrams but I cannot find any open source planning libraries that use this ...

I am aware that algorithm for monocular SLAM is complex compared to stereo SLAM. But my question is if by any means it is possible to do SLAM using one camera why one should use two cameras to do the ...

I am currently considering joining the MicroTransat challenge and develop an autonomous boat able to survive the harsh Ocean environment.
However, as for security and to ensure the boat doesn't sink ...

I'm using ROS indigo in my project and all the nodes and visualisation (Rviz) seems to be functional when I launch the program using roslaunch. Here are the sensors used in the scooter:
Hokuyo Lidar
...

As you know in Bug algorithm there is a simplifying assumption that says the robot has no size and can fit between any arbitrarily small gap in the map. How can we overcome the challenge of robot size....

I am building a rover which can navigate autonomously. I do not want to use wheel encoders for generating robot odometry since it causes drifts due to slippage etc.
I want to use GPS for generating ...

I have created a robot model in solidworks and exported in solidworks to urdf plug-in. When exporting the co-ordinates of the model is misaligned which is causing problem while using in ROS.
As you ...

I have added hokuyo laser plug-in to mu urdf file. I successfully launched the robot in gazebo and done required changes to visualize it in rviz. I didn't get any error but the laser scan results are ...

I have built my differential drive mobile robot in solidworks and converted that to URDF file using soliworks2urdf converter. I successfully launched and robot and simulated with tele-operation node. ...

I bought a 3-axis magnetometer (Similar to this one ) And plugged into an Arduino in order to read the heading value.
I mounted it on my robot and I drove with the robot for around 30 meters, turned ...
